Coal Mill - an overview ScienceDirect Topics
The situation is further complicated by the ‘mill reject’ streams that reject undesirable material (tramp metal and non-coal bearing rock) from the mill. Generally, the following steps illustrate the path through a VSM: • The raw (coal) feed enters the mill through a central delivery pipe and falls under gravity onto the Grinding Table; •
